Extra cilantro inspires an impromptu pesto.
Pesto had its heyday in the culinary sun some time ago, when chefs concocted versions of the Italian-style uncooked sauce using all manner of ingredients in all kinds of dishes.
But pesto will never really fall out of favor, in part because it’s such a great way to use leftover herbs. Certainly in summer, when bunches of fresh basil sell for a song at farmer’s markets, home cooks and professional chefs alike whip up batches of the pesto. And as Debbie Arrington notes in the Sacramento Bee, winter herbs work just fine, too.
You can play with pesto’s formula, using different herbs, cheeses, and nuts to vary the flavor and reflect the season.
Traditional pesto is nothing more than an uncooked sauce made of fresh basil, garlic, pine nuts, Parmigian0-Reggiano cheese, and olive oil pounded in a mortar and pestle. These days, most people use a food processor or blender. Of course, you can play with that formula, using different herbs (arugula, cilantro, mint, sage, etc.), cheeses (Manchego, say), and nuts (walnuts, pecans, hazelnuts, you name it). You can add other ingredients–a touch of cracked red pepper for a heat, perhaps, or a squeeze of lemon juice for bright acidity. I came up with this version to use a bunch of cilantro sitting in the crisper.
